And thou wouldst have thought that they were awake, whereas they lay asleep. And We caused them to turn over repeatedly, now to the right, now to the left; and their dog [lay] on the threshold, its forepaws outstretched. Hadst thou come upon them [unprepared,] thou wouldst surely have turned away from them in flight, and wouldst surely have been filled with awe of them. 18 And so, [in the course of time,] We awakened them; and they began to ask one another [as to what had happened to them]. One of them asked: "How long have you remained thus?" [The others] answered: "We have remained thus a day, or part of a day." Said they [who were endowed with deeper insight]: "Your Sustainer knows best how long you have thus remained. Let, then, one of you go with these silver coins to the town, and let him find out what food is purest there, and bring you thereof [some] provisions. But let him behave with great care and by no means make anyone aware of you: 19 For, if they appear in front of you, they will stone you to death or restore you to their religion. Then you will never prosper' 20 And even so We made them stumble upon them, that they might know that God's promise is true, and that the Hour -- there is no doubt of it. When they were contending among themselves of their affair then they said, 'Build over them a building; their Lord knows of them very well.' Said those who prevailed over their affair, 'We will raise over them a place of worship.' 21 They will say there were three, the fourth of them being their dog; and they will say there were five, the sixth of them being their dog - guessing at the unseen; and they will say there were seven, and the eighth of them was their dog. Say, [O Muhammad], "My Lord is most knowing of their number. None knows them except a few. So do not argue about them except with an obvious argument and do not inquire about them among [the speculators] from anyone." 22
